Interstate water disputes are as American as apple pie. States often think a neighboring state is using more than its fair share from a river, lake or aquifer that crosses borders.
Climate stresses are raising the stakes. Rising temperatures require farmers to use more water to grow the same amount of crops. Prolonged and severe droughts decrease available supplies. Wildfires are burning hotter and lasting longer. Fires bake the soil, reducing forests’ ability to hold water, increasing evaporation from barren land and compromising water supplies.
States should put at least as much effort into reducing water use as they do into litigation, because there are no guaranteed winners in water lawsuits.
